This paper's topic is sleep habits and early childhood fears. The paper is divided into two parts: theoretical part and research about sleep habits and early childhood fears. The paper deals with the possibilities and ways of resolving the habitual problems of going to bed and sleep itself but also the issue of early childhood fears. The method used in the research was the questionnaire given to parents who were willing to help the author of the work in collecting the information needed to complete the research. The research about sleep habits and early childhood fears was conducted at Cres' kindergarten. Results obtained are given in this paper. The results don't vary from the data mentioned in the theoretical part of the paper. Most of the children have early fears regarding something new and unknown and most of the parents are inconsistent in creating the sleep habits of their children. The goal of this work, except pointing out the existence of issues with creating sleep habits and existance of early childhood fears, is pointing out the fact that the real issue are the parents, not the children. The theoretical part of the paper contains depictions of sleep habits and their differences, definitions of discernment between a nightmare and nightfears, as well as their possible solutions. There are lots of authors who wrote about sleep habits, sleep problems and early childhood fears. Regardless of how many Croatian authors have written about the sleep habits and early childhood fears, it can be inferred within this work that the children in Croatia mainly face the same problems as their peers in developed countries of the world.
